Ok so it’s easy to put together, everything just basically snaps together, which I thought wasn’t very safe, but whatever. But it seems sturdy enough. My 19month old daughter who weighs 27lbs does just fine on it. She loves it and we have it inside the playroom during cold weather. She can’t stand up all the way in the little house part so I wish it was taller. But overall pretty good for getting energy out on cold days. Buying one for the grandparents house too.
